Abstract
The disclosure concerns a tunable logarithmic detector amplifier (TLDA) system where dynamic tuning functionality is applied to resonant circuits used for feedback control as well as applying tuning to the amplifier. Control signals for the tuning function are generated from the baseband processor. The control of the amplifier tuning and resonator tuning can be performed from information derived from baseband where metrics such as SNR, SINR or CQI are used to optimize system performance. Bandwidth and sensitivity of the receiver are key specifications targeted for optimization using this technique. This technique can be implemented in designs where a wide bandwidth is required.
